It's not hard to see why the "Syrian rebels" are losing so badly to the Syrian government forces. Guess who has more support from the Syrian people. Applying the principles of 4GW, it should be obvious that Assad is going to win, because despite being an Alawite, he is still Syrian. The so-called rebels no more represent the Syrian people than the US military for whom they are a proxy do, which is why the usual rules about 4GW insurgencies don't apply to them. They're invaders, not insurgents.
